[GitHub] [apisix] zlhgo opened a new issue, #6879: help request: maybe upstream response time is not true

zlhgo opened a new issue, #6879:
URL: https://github.com/apache/apisix/issues/6879

   ### Description
   
   I added `os.execute("sleep " .. 3)` code to the front of _M.http_access_phase() function of the apisix/init.lua file.
   
   then
   ```
   curl flask-demo.dev.apisix.net:9080
   ```
   
   nginx access log output:
   ```
   127.0.0.1 - - [19/Apr/2022:14:34:41 +0800] flask-demo.dev.apisix.net:9080 "GET /headers HTTP/1.1" 200 20 request_time=3.005 "-" "curl/7.64.0" 127.0.0.1:8102 200 upstream_response_time=3.004 "http://flask-demo.dev.apisix.net:9080"
   ```
   
   file-logger plugin output:

   ```
   
   Perhaps the 3 seconds consumed by the sleep function and the other lua code execution time should not be counted in the upstream response time.
   
   
   ### Environment

   - Operating system (run `uname -a`):
   - OpenResty / Nginx version (run `openresty -V` or `nginx -V`):
